Systems and methods are provided for encrypting and decrypting data using visually encoded ciphertext. The method includes selecting, using a graphical user interface coupled to an electronic device, one or more portions of a document to be encrypted, visually encoding the selected one or more portions of the document, generating a visual representation, wherein the visual representation corresponds to encrypted content, and replacing the selected one or more portions of the document with the visual representation. The method further includes displaying, to the user, the visual representation, capturing the visual representation using one or more cameras, decoding the visual representation, obtaining the encrypted content, and decrypting the encrypted content, generating decrypted content.

Network management

A method implemented in a network apparatus used in a network is disclosed. The method comprises collecting information about network topology from a network controller, collecting information about data movement, deciding routing in the network according to the information about network topology and the information about data movement, and providing information about the routing to the network controller, wherein the network controller enforces the routing in the network. Other methods, apparatuses, and systems also are disclosed.

Data processing

A method for policy-aware mapping of an enterprise virtual tenant network includes receiving inputs from a hosting network and tenants, translating resource demand and policies of the tenants into a network topology and bandwidth demand on each link in the network; pre-arranging a physical resource of a physical topology for clustering servers on the network to form an allocation unit before a VTN allocation; allocating resources of the hosting network to satisfy demand of the tenants in response to a VTN demand request; and conducting a policy aware VTN mapping for enumerating all feasibly resource mappings, bounded by a predetermined counter for outputting optimal mapping with policy-compliant routing paths in the hosting network.

Systems and methods for discovering a set of applications that run on a network are disclosed. In accordance with one method, aggregate traffic volumes are determined for pairs of nodes on the network over a plurality of time intervals. The method further includes building a traffic matrix denoting each of the pairs of nodes and denoting respective aggregate traffic volume histories of each of the pairs of nodes that are based on the determined traffic volumes. In addition, the traffic matrix is formulated as a combination of bases vectors that model the set of applications. The bases vectors are determined by applying a covariance matrix adaptation evolutionary strategy based on the traffic matrix. An indication of the set of applications based on the bases vectors is output.
